Kernel Panic?

I tryed up[censored] fedora, redhat 9.0, and redhat 8.0 to 2.6 but whenever i did it, after the grub it came to kernel panic

i followed the steps

Quote:

1. download kernel source .tar.gz or .tar.bz2 format from www.kernel.orgfor example there will be file like linux-2.4.22.tar.gz

2. copy it to /usr/src by following command:

cp filename.tar.gz /usr/src

3. cd to the /usr/src directory

cd /usr/src

4. issue the following command to uncompress the file

tar -xzf linux-2.4.22.tar.gz

it will extract kernel sources to /usr/src directory

right now directory for 2.4.22 will be

/usr/src/linux-2.4.22

5. create a symbolic link /usr/src/linux to point to /usr/src/linux-2.4.22 using the ln -s command:

cd /usr/src ln -s linux-2.4.22 /usr/src/linux

6. cd to /usr/src/linux

cd /usr/src/linux

7. now issue following command

make xconfig

this will start a gui based configuration tool...where u will select the kernel options.Make sure you set fat, vfat and ntfs support and other required options.

Also it is recommended, that when the configuration is complete, you save the settings to a file on the hdd using the save to file option, so that the next time you recompile, you can directly load the configuration from the saved file and proceed to the next step

8. issue following command

make dep

9. issue following command

make clean

10. issue following command

make modules

11. issue following command

make modules_install

12. issue following command

make bzImage

now when make bzImage is done. open your grub.conf and make a backup copy of it, just to be careful forexample i did this cp /etc/grub.conf /etc/grub.backup.

13 . issue following command

make install

after make install is complete. open /etc/grub.conf and check if the entry of old kernel is still there or not. if its not there, open the backup of grub.conf that we created and copy and paste the entry of old kernel into grub.conf. if the old kernel entry is already there, thats great.

now reboot your system and enjoy new kernel.

Note: There is a way to compile kernel through rpms, but doing it source way lets u experience some cool speed plus totally your own kernel configurations, so i prefer this

which was in another thread maybe i shouldnt be trying this method beiang a noob any advice

No offense but, I guess there is no need for modutils and module-init-utils, if he just wants to compile it. however, modutil and module-init-utils are required for making kernel work .

I compiled my 2.6.1 kernel, just with usual source way (the one i have mentioned) without modutils and module-init-utils. it worked and it still boots up, but this is another story i have difficulties with some devices working even if after installing modutils and module-init-utils.

Alright the first step to this incident is.... making your symbolic link after uncompressing the kernel-2.x.x-tar.gz in your /usr/src... now make sure you don't have /usr/src/linux, if so delete it, and relink your symbolic link.. then go in either using 'make menuconfig' or 'genkernel --menuconfig all", so you can go in and do your own kernel configuration. After doing so, if you chose to use 'make menuconfig' you'll have to copy down some things: cp arch/i386/boot/bzImage /boot/kernel-2.x.x cp System.map /boot/System.map-2.x.x cp .config /boot/config-2.x.x

If you chose 'genkernel --menuconfig all' you must then wait foro that to complete, and then proceed to make the changes to grub.

After doing these steps you are able to change your /boot/grub/grub.conf file. I prefer leaving everything as it is, and adding to it, so I can revert if needed. This is how mine looks:
